To all whom it may concern:

Be it'known that we, VVILLIAM L. BURNER D. BENBOW, citizens of the lumb'us, in the county of and usefullmprovements in Dump-Cars, of which the following is a specification.

Our invention relates to devices for .dumping acar bed pivotally mounted, preferabl; a side dumping car of the type in dumping operation, the side door is held aloft and swings outwardly which the lading is dis- 1 of the caryibed reta ns its closed position.

- The chief feature of .the invention is .the use of a vertically disposedlifting bar to hold the door aloft and one or more pivotally I its desired open mounted members interposed between the door and the lifting bar in such way as to be actuated by'the bar to swing the door to mg operation and to affect its retraction when the car is being restored to normal position.

' In the drawings hereto attached and hereby made a part of this specification, Figure 2 1 shows our devices in place on the .end

illustrated, Fig. 2 shows the devices when the car is bf a car, a portion only of the car being at its maximum dumping position.

In Figs. 3 and 4 a roller member has been introduced.

Referring to the drawings, 1 is a car underframe, 2

connected at 15 with a door actuating member 16 pivotally mounted on the door supporting bar 1 at 7 the same point at which the door is hung on the said bar 4. The operation of the device is as follows Assume, that the car bed is to be dumped toward the left, as illustrated in Fig. 2, the bar 9 is lowered through the tilting of the car bed until the pin 11 engages the upper end of the slot 10 whereupon the door is held aloft, and as the travel of the car bed member 16 is pivoted at the upper angle thereof adjacent to the door whereas the actuation thereof 'takes place through the pivotal connection 15 at the other upper angle thereof. \Ve thus utilize a. freeswinging member appropriately pivoted for actuation by the door supporting memher, to throw the door to its desired open position.

A modification is shown in Fig. 3, where in the link 13 is omitted and its function is performed by providing a hook 17 at the upper end of the door lifting bar 9 procided with a roller 18 which engages the member 16 and actuates the same directly.

In Fig. 1 the member 16 is secured rigidly on the door, and is actuated-by the hook and roller construction shown in Fig. 3.

Upon returning the car bed to normal position themember 16. is swung on the pivot 7 through the pivotal connection at 15 with the link 13, and the door 6 drops back gradually to its normalposition behind the .lock 8. The member 16 may appropriately b described as a cam member swinging about the pivot 7 and actuated by a force acting on the pivot point 15.
